Abstract
PURPOSE:To obtain high-purity and fine titanium diboride without the need of grinding process, by reaction between titanium nitride powder and boron powder under each specified monoxidative atmosphere and temperature. CONSTITUTION:The objective powder can be obtained by bringing titanium nitride powder and boron powder into contact with each other at 1,000-1,800 deg.C under a nonoxidative atmosphere except nitrogen gas one to perform reaction. In this production process, nitrogen is formed as a by-product, therefore, use of a nitrogen gas as an inert gas will hamper the reaction, and the nitrogen gas should thus be eliminated from nonoxidative atmospheres. Hydrogen gas etc. inert to the reaction feedstock can be used instead of inert gases; alternatively, depressurization is permitted to produce nonoxidative atmosphere. Removal of the nitrogen gas produced by the reaction under reduced pressure out of the reaction system will further enhance the reaction rate.
